Yes, they exist. (And no, they're not the kind you have by yourself in your bedroom as you ugly cry over the fact that you didn't get tickets to that thing you love). Technology has taken us this far and it's amazing. Through the use of holographic images of some of our favorite artists, these digital shows are able to create a whole new concert experience.

Credits to whatever started this new trend are given to the Tupac Shakur Hologram performance at the Coachella Festival in 2012. [Watch the video ﻿here﻿] People stood in awe as the late rapper performed alongside Snoop Dogg onstage. It had headlines and onlookers wondering which deceased icon could be "resurrected" next.

How does it work? Well, here's a quick science lesson:

Pretty cool, right? Think of the possibilities. (Maybe your favorite band at your next birthday party or perhaps your celebrity crush for a prom photo op?)

And it's not just Tupac taking the concert world by storm as a resurrected image. Virtual concerts are pretty popular in the K-pop scene as well. You could see PSY performing the ever-famous K-pop hit Gangnam Style in a digital show onstage in the photo below.

In fact, Asian music companies have been using holographic technology to change up the generic concert experience since the 90's. Stars who are unable to go on tour and travel around the world, alongside deceased favorites, are brought to the stage through this amazing innovation. A Korean music label called Yang Goon Entertainment are on a mission to bring virtual concerts to 20 theme parks around the globe by the year 2015.

Another famous name in the digital concert world would be an entirely virtual Japanese pop star known as Hatsune Miku has become a hit. She's a computer-generated celebrity loved by many in the Anime community.

Which artist do you think will be featured on the virtual concert stage next?
